ABSTRACT
The study was carried out in 2008 at Hassan UsmanKatsina Polytechnic farm to study the effects of rate of poultry manure application on the growth and yield of irrigated celery (Apium Graveolens). The experimental design used in this research was a randomized complete block design. The treatments consisted of 5 level of poultry manure applied at rate 0 (control), 10, 20, 30, 40 kg/ha-1. Observations were made on plant height, number of leaves, stem diameter and fresh weight of leaves. Data collected were subjected to analysis of variance. Based on the analysis of variance carried out the result showed that 20kg/ha-1 of poultry manure application gave statistically taller plants, higher number of leaves and stem diameter than other treatments but are not significantly different on fresh weight of leaves if compared to 40 kg/ha-1 of poultry manure application.
